Understanding the origin of the isotopic dichotomy between carbonaceous chondrites (CCs) and non-carbonaceous (NCs) meteorites, especially in Ti (ε⁵⁰Ti) and Cr (ε⁵⁴Cr), is essential for exploring the early evolution of the Solar System and the planetesimal formation. Calcium-aluminum-rich inclusions (CAIs), the oldest Solar System condensates rich in CCs, control the isotopic compositions of refractory elements in CCs. However, the Ti-Cr isotopic compositions of CCs cannot be solely ascribed to commonly studied coarse-grained CAIs (CGs).

Subsidence of Transantarctic Mountains crust, induced, for example, by long-term crustal extension before Cenozoic exhumation and Cretaceous–Cenozoic rifting, has been previously inferred from geologic and thermochronological records. There are, however, uncertainties about the thermochronological history of basement rocks in the Transantarctic Mountains, particularly for the Paleozoic following the late Neoproterozoic to early Paleozoic Ross-Delamerian orogeny. Here we show that K-feldspar ⁴⁰Ar/³⁹Ar cooling ages (∼350–150 °C closure temperature) from granitoid bodies collected from a large region across the Transantarctic Mountains are consistent with local punctuated exhumation of basement highs in the Silurian–Devonian, Carboniferous–Triassic, and Cretaceous–Paleocene. Times of increased exhumation correlate with periods of erosion and nearby sedimentation, including the Late Paleozoic Ice Age glaciation. They also correlate with the known timing of outboard plate-margin tectonism, suggesting the presence of dynamic inboard Paleozoic-Mesozoic landscapes influenced by cycles of crustal deformation and possibly, glaciation along the Pacific-Gondwana margin. The results indicate a geologic history like Antarctica’s contiguous margin in eastern Australia and highlight the importance of collecting comprehensive time-temperature data to fully understand the evolution of bedrock relief.

This significant conflict hampers understanding of the timing of activity of the surrounding fault systems, and the uplift and growth mechanism of the northern Tibet. In this study, we sampled tubular carbonate veins and abundant paleosol calcareous nodules from the Lulehe Fm. Using calcite U-Pb dating and clumped isotopes, we obtained an average age of 50.8 ± 2.8 Ma and formational temperatures of the nodules ranging from 39.6 ± 2.3 °C to 43.2 ± 3.4 °C in the Honggou section, and 28.2 ± 0.7 °C to 34.3 ± 4.2 °C in the Hongshan West section. Furthermore, by applying elevation-dependent isotopic and clumped temperature lapse rates, we reconstructed the paleoelevation of the Qaidam Basin during the early Eocene to be 1.6 ± 0.98 km. Our findings align more closely with the traditional stratigraphic framework of the Lulehe Fm, indicating that initial sedimentation in the Qaidam Basin occurred during the early Eocene. Moreover, we provide a quantitative estimate of the basin's paleoelevation during its early stage.

While geophysical imaging has documented low seismic anomalies associated with mantle upwelling. However, the subduction of an oceanic triple junction is a complex process that has been identified through tectonic reconstructions but has not been tested yet. In this contribution, we provide a simplified numerical model to understand the geodynamic and thermal consequences due to a subducted oceanic triple junction. We conducted 2D thermomechanical simulations with appropriate initial conditions to reproduce the long-term effects (up to 14 Ma) of successive mid-ocean ridge subduction. Model results show migration of partial melts in the upper mantle that lead to the generation of ridge jumps, slab remnants and a new subduction zone, having an impact in tectonic reorganizations and terrane accretion. In addition, long-term thermal anomalies (60-90 °C/km) in the overriding plate can only be developed with a proper combination of geodynamics settings and erosional conditions (1 mm/yr).

Despite decades of research, salt extrusion and flow rates at the surface remain poorly characterized, even with frequent confusing terminology. In our study, we aim to separate both phenomena at one of the best test sites on Earth, Mt. Sedom, a prominent salt extrusion site in a tectonically active basin. We utilized InSAR (Interferometric Synthetic Aperture Radar) techniques to measure surface salt motion with high temporal resolution, analyzing 9.5 years of Sentinel-1 data to derive both vertical and horizontal displacement components. Our approach improves previous estimates that used only line-of-sight (LOS) measurements. We are able to estimate vertical uplift rates directly above the salt extrusion channel location inferred using mechanical modeling. We propose that these estimates are a much closer representation of the actual salt extrusion rates, and largely independent of the typically overlapping surface gravity-driven flow dynamics. The InSAR time-series suggests that thermal expansion is a first-order driver of the observed seasonal uplift and subsidence patterns. Moreover, for the first time in Mt. Sedom, displacement changes in response to weather (rainfall) were inferred to be statistically significant. We conclude that any rainfall event, regardless of its magnitude, might be sufficient to enhance salt flow rate. This can be explained as a result of salt dissolution and increased gravity-driven downslope movement in the salt glacier as the salt becomes wet, due to increased surface load or reduced viscous/frictional forces. By integrating InSAR measurements, mechanical modeling, and meteorological data, this study provides new constraints on surface salt motion at Mt. Sedom, improving our understanding of its driving mechanisms. Most importantly, our results reveal an immediate response of salt motion to rainfall, providing new insights into interactions between atmospheric and crustal processes.</div></div>","PeriodicalId":11481,"journal":{"name":"Earth and Planetary Science Letters","volume":"664 ","pages":"Article 119446"},"PeriodicalIF":4.8,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144072244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we report measurements of the elastic properties of (Mg_0.9Fe_0.1)₂SiO₄ ringwoodite (Rw90), the dominant component of pyrolite between 520 km and 660 km depths, using pulse-echo ultrasonic interferometry combined with synchrotron X-radiation in the multi-anvil press up to 21 GPa and 1650 K.

In contrast, we find that pyrolite would not produce a large and sharp <em>V</em>_P discontinuity at 660 km as the jump in <em>V</em>_P caused by the decomposition of Rw90 is too small. A homogenous assemblage of pyrolite cannot, therefore, currently explain the seismic features in the lower MTZ.
